Developers, designers, engineers, and creators can no longer afford to pass responsibility for identity and data security onto others. Web developers who don't understand how to obscure data in transmission, for instance, can open security flaws on a site without realizing it. With this practical guide, you'll learn how and why everyone working on a system needs to ensure that users and data are protected. Authors Jonathan LeBlanc and Tim Messerschmidt provide a deep dive into the concepts, technology, and programming methodologies necessary to build a secure interface for data and identity-without compromising usability. You'll learn how to plug holes in existing systems, protect against viable attack vectors, and work in environments that sometimes are naturally insecure. Understand the state of web and application security today Design security password encryption, and combat password attack vectors Create digital fingerprints to identify users through browser, device, and paired device detection Build secure data transmission systems through OAuth and OpenID Connect Use alternate methods of identification for a second factor of authentication Harden your web applications against attack Create a secure data transmission system using SSL/TLS, and synchronous and asynchronous cryptography

Java has taken the computing world by storm - now it arms itself to conquer telecommunications!

What links today's hottest programming language to telecommunications? The same characteristics that brought about Java's remarkable success on the Internet: its platform independence and mobility.

Recent developments such as JAIN (Java APIs for Integrated Networks), JAIN Parlay and the Java Telephony API equip Java for the next generation of telecommunications systems and networks. The authors, all practitioners at companies such as Sun Microsystems and Telcordia, provide the first comprehensive overview of how Java will be employed in areas such as call control, intelligent networking, PSTN/Internet convergence, and integrated network management.

As well as providing a high-level survey of architectures and protocols, Java in Telecommunications also gives detailed guidance on implementation strategies for the brand new, still evolving, technologies:

• call and multimedia processing;

• Voice Over IP (VOIP) Telephony;

• eXtensible Markup Language (XML);

• Enterprise Java Beans (EJB).

How often do you hear people say things like this? "Our JavaScript is a mess, but we're thinking about using [framework of the month]." Like it or not, JavaScript is not going away. No matter what framework or "compiles-to-js" language or library you use, bugs and performance concerns will always be an issue if the underlying quality of your JavaScript is poor. Rewrites, including porting to the framework of the month, are terribly expensive and unpredictable. The bugs won't magically go away, and can happily reproduce themselves in a new context. To complicate things further, features will get dropped, at least temporarily. The other popular method of fixing your JS is playing "JavaScript Jenga," where each developer slowly and carefully takes their best guess at how the out-of-control system can be altered to allow for new features, hoping that this doesn't bring the whole stack of blocks down. This book provides clear guidance on how best to avoid these pathological approaches to writing JavaScript: Recognize you have a problem with your JavaScript quality. Forgive the code you have now, and the developers who made it. Learn repeatable, memorable, and time-saving refactoring techniques. Apply these techniques as you work, fixing things along the way. Internalize these techniques, and avoid writing as much problematic code to begin with. Bad code doesn't have to stay that way. And making it better doesn't have to be intimidating or unreasonably expensive.

For years now, web developers have used powerful application servers like PHP and Node that could create our web apps. But recently there's been a shift between how much we can do on an application server versus how much we can do on the browser itself-as well as what we can do on a mobile app. This practical book shows readers how static site generators provide a powerful middle ground between a full app server deployment and a simple collection of static files. Written by two leading developers in the JavaScript community, this book teaches front-end designers, front-end developers, web developers, and web designers how static site generators work, the benefits you can expect, and what options are available. You'll learn how to deliver static site files to the end user exactly as they are on the server, without using a server-side language or a database, using HTML, CSS, and JavaScript. Static websites today are just like vinyl LPs: they're coming back. With this book, you'll discover just how these websites still fulfill a vital need for bloggers as well as people who just want to disseminate information.
